January 2014 (has links)
引子: 共晶技術和納米沉澱技術於近年被廣泛討論能改進藥物性質和提高體內性能。本論文研究旨在將該兩種技術嘗試應用於五種模型藥物中,分別是薑黃素(CUR),氟比洛芬(FLU),布洛芬(IBU),酮洛芬(KET) 和環氧洛芬(LOX)。這些藥物均難溶於水,擁有較差機械性質,相對高的親油性和潛在治療腦退化症的功用。在共晶技術中,藥物將會與煙酰胺(NCT)先溶於在溶劑中,透過蒸發以誘發共晶產生。另一方面,瞬時納米沉澱(FNP)技術會將藥物溶液(包含穩定劑)與反溶劑在封閉衝擊射流混合器(CIJM)或多入口渦旋混合器(MIVM)快速混合,生成納米藥物。 / 方法: 將藥物和NCT溶於乙醇中,應用旋轉蒸發或簡單蒸發生成共晶。透過不同的檢測方法,包括X射線衍射,差示掃描量熱法,熱重分析,吸濕分析,傅立葉變化紅外線光譜,特性溶出速率量度法和壓實分析將共晶檢定。另一方面,利用CIJM或MIVM,藥物在不同的混合速率,溶劑性質,聚乙二醇-聚乳酸(穩定劑)分子重量或藥物對聚合物比的工藝環境下載入於納米粒子中。生產出來的納米藥物會利用動態光散射測定粒徑; 電泳光散射法測定zeta電位; 掃描電子顯微鏡和原子力顯微鏡測定粒子形貌和其表面性質; X-射線光電子能譜測定表面成分; 高效液相色層分析測定載藥量和包封率。 / 結果: 利用旋轉蒸發,高純度的1:1 IBU-NCT 和FLU-NCT 的共晶能成功生成,但KET-NCT和LOX-NCT 共晶則不能獲得。低純度的CUR-NCT 共晶可根據相同技術取得。相比原來藥物而言,IBU-NCT 和FLU-NCT 共晶均有較好的機械性質,抗吸水性和溶解速度。而在FNP研究中,証實了混合速率,溶劑性質,聚乙二醇-聚乳酸(穩定劑)分子重量或藥物對聚合物比均對生產出來的納米粒子的粒徑有重要影響。另外,納米粒子的穩定性可籍添加輔助穩定劑(如PVA)大幅提高。XPS分析証實輔助穩定劑能與在粒子表面的聚乙二醇起相互作用,更佳地保護粒子。而在一系列對四種不同的洛芬藥物的實驗中,多次線性回歸分析指出三種有關藥物的溶液性質(即溶解度,分配係數和酸度系數)會對生成的納米粒子的粒徑和包封率有顯著影響。 / 結論: 將IBU和FLU與NCT結成共晶能同時提高其機械性質,抗吸水性和溶解速度。而在FNP中,優化不同工藝參數能有效控制納米藥物的粒徑,形態,表面性質和穩定性。 / Introduction: In recent years, cocrystallization and nanoprecipitation have gained increasing popularity as viable strategies for improving the pharmaceutical properties and in vivo performance of drugs. The present thesis was aimed at assessing these two approaches for potential applications in pharmaceutical formulation and manufacture with five model drugs, viz. curcumin (CUR), flurbiprofen (FLU), ibuprofen (IBU), ketoprofen (KET) and loxoprofen (LOX). Selection of these drugs for the study was guided mainly by their poor water solubility, poor compactibility, typical drug‘s lipophilicity (log P =3-5), and potential for treatment of Alzheimer‘s disease. Cocrystallization was induced by the attainment of a sufficient supersaturation level through rapid solvent removal from a solution containing the drug and the coformer, nicotinamide (NCT), while flash nanoprecipitation (FNP) was achieved by rapid and homogenous mixing of drug solution (with stabilizer and co-stabilizer if required) with antisolvent in the mixing chamber of a specially designed confined impinging jet mixer (CIJM) or multi-inlet vortex mixer (MIVM). / Methods: Cocrystals were prepared by rotary solvent evaporation or slow evaporation of a solution of drug and NCT in ethanol, and characterized by powder X-ray diffraction, differential scanning calorimetry, thermogravimetry, moisture sorption analysis, Fourier transform infrared spectroscopy, intrinsic dissolution rate (IDR) measurement and compaction analysis. Polymer-stabilized drug nanoparticles were prepared by FNP using a two-stream CIJM or four-stream MIVM under defined conditions of varying flowrate, solvent type, molecular weight of amphiphilic diblock (PEG-PLA) copolymer (stabilizer), or drug-to-copolymer ratio. The resulting nanoparticles were characterized for particle size by dynamic light scattering; zeta potential by electrophoretic light scattering; particle morphology and surface properties by scanning electron microscopy and atomic force microscopy; surface composition by X-ray photoelectron spectroscopy (XPS); and drug loading and encapsulation efficiency (EE) by high performance liquid chromatography. / Results: Phase-pure 1:1 cocrystals of IBU and FLU with NCT were obtainable by rotary solvent evaporation, but not slow evaporation. Similar solvent removal failed to cause any cocrystal formation for KET and LOX while inducing partial cocrystal conversion for CUR. Both IBU-NCT and FLU-NCT cocrystals displayed enhanced IDR, reduced moisture sorption and improved tabletability compared with the individual profen crystals. FNP studies using the MIVM confirmed the flowrate, solvent type, molecular weight of PEG-PLA copolymer, and drug-to-copolymer mass ratio being important process variables for controlling particle size and particle stability. Particle stability could be enhanced with a hydrophilic co-stabilizer (e.g., PVA). Such co-stabilizers possibly act by binding to the PEG corona at the particle surface to reinforce the protective steric barrier, as substantiated by XPS data. Comparative studies on nanoparticle production by FNP for the four profens indicated that three structure-related intrinsic solution properties of the profens, namely, water solubility, log P and pKa, were important determinants of the particle size and EE of nanoparticles, as determined by multiple linear regression analysis. / Conclusion: Cocrystallization with NCT can simultaneously improve the tableting behavior, hygroscopicity, and dissolution performance of IBU and FLU. Proper optimization of the process variables in FNP is critical to the controlled production of polymer-stabilized drug nanoparticles with consistent properties and storage stability. / Detailed summary in vernacular field only. / Detailed summary in vernacular field only. / Detailed summary in vernacular field only. / Detailed summary in vernacular field only. / Chow, Shing Fung. / Thesis (Ph.D.) Chinese University of Hong Kong, 2014. / Includes bibliographical references (leaves 224-247). / Abstracts also in Chinese.

The effect of spinal manipulative therapy in conjunction with transcutaneous flurbiprofen in the treatment of mechanical low back pain

Proctor, Matthew Charles 04 June 2012 (has links)
M.Tech. / Purpose: This study aims to compare the effects of spinal manipulative therapy to the lumbar spine and/or pelvis, and spinal manipulative therapy to the lumbar spine and/or pelvis in conjunction with the application of transcutaneous flurbiprofen patches in the treatment of sub-acute/chronic mechanical low back pain with regards to pain, disability and lumbar spine and pelvic range of motion. These effects were based on a questionnaire consisting of a Numerical Pain Rating Scale, and an Oswestry Low Back Pain and Disability Questionnaire, and on lumbar spine range of motion (ROM) readings taken using a digital inclinometer. The questionnaire was completed and the ROM readings taken prior to treatment on the first, fourth and seventh consultations.

Early Detection of Dietary-Induced Periodontal Bone Loss and the Effect of Flurbiprofen Administration in the Syrian Hamster

Child, Michael E. January 1991 (has links)
Indiana University-Purdue University Indianapolis (IUPUI) / Root surface caries is an increasing problem in the United States as more of the population are retaining their teeth to an older age. The disease requires the recession of gingival tissue and resorption of alveolar bone prior to exposure of the root surface. Animal models for root surface caries provide a means to investigate the etiology and treatment of the disease. The Golden Syrian hamster has been used as a model, and alveolar bone loss and root exposure are induced by feeding the animals a high glucose diet. Significant bone loss, when compared to control groups, is usually detected within five weeks. At present, the use of non-steroidal anti-inflammatory drugs in the treatment of periodontal disease is an area of great interest. As there is a role of host response in the alveolar bone destruction seen in periodontitis, inhibition of this prostaglandin-mediated process may provide a means of treatment. Flurbiprofen (Ansaid™, Upjohn Co., Kalamazoo, Ml) has been widely studied and appears to inhibit this bone loss in a variety of animals, including man. The purposes of the study were to determine if the early alveolar bone loss occurring after three, four and five weeks' exposure to the high carbohydrate diet could be quantitated with fluorescent bone labels, and if this bone loss could be inhibited by daily administration of flurbiprofen. The animals received a series of four intraperitoneally-injected fluorochrome labels over a one-month period, then were fed ground lab chow, the high carbohydrate MIT-200GI diet or the MIT-200GI diet plus flurbiprofen. At the end of three, four and five weeks, animals were euthanized, and the mandibles were prepared for analysis. Statistical analysis of gross and histomorphometric measurements detected no significant differences between the experimental groups. It is suspected that the diets failed to produce periodontal disease in this experiment, possibly due to changes in the oral microflora caused by administration of tetracycline as the final bone label. There was much variation in the presence of bone labels, but they were able to provide the growth velocity of the alveolar complex. Flurbiprofen administration produced no measurable effects, but the animals did tolerate the dosage given. Future studies should consider variation of the labels and a different route of administration.

Exploring Microstructural Changes in Structural Analogues of Ibuprofen-Hosted In Situ Gelling System and Its Influence on Pharmaceutical Performance

Patil, S.S., Venugopal, E., Bhat, S., Mahadik, K.R., Paradkar, Anant R 2015 February 1926 (has links)
No / The present work explores inner structuration of in situ gelling system consisting of glyceryl monooleate (GMO) and oleic acid (OA). The system under study involves investigation of microstructural changes which are believed to govern the pharmaceutical performance of final formulation. The changes which are often termed mesophasic transformation were analysed by small angle X-ray scattering (SAXS), differential scanning calorimetry (DSC), rheology and plane polarised light (PPL) microscopy. The current work revealed transformation of blank system from W/O emulsion to reverse hexagonal structure upon addition of structural analogues of ibuprofen. Such transformations are believed to occur due to increased hydrophobic volume within system as probed by SAXS analysis. The findings of SAXS studies were well supported by DSC, rheology and PPL microscopy. The study established inverse relationship between log P value of structural analogues of ibuprofen and the degree of binding of water molecules to surfactant chains. Such relationship had pronounced effect on sol-gel transformation process. The prepared in situ gelling system showed sustained drug release which followed Higuchi model.

The effectiveness of dry needling versus Flurbiprofen LAT patch in the treatment of myofascial pain syndrome of the upper Trapezius muscle

Veerasamy, Seerouven 20 May 2014 (has links)
Completed in partial compliance with the requirements for the Master's Degree in Technology: Chiropractic, Durban University of Technology, 2014. / Background: Dry needling is known to be effective and efficient in the treatment of myofascial pain syndrome; pragmatically however, patients utilise Flurbiprofen LAT patches as home therapy anticipating similar results. This may not be true and thus, this study aimed to investigate the effectiveness of dry needling versus Flurbiprofen LAT patches in the treatment of myofascial pain syndrome of the upper Trapezius muscle. Methods: This ethics approved, prospective, randomized, single blinded (blinded assessor), comparative clinical trial required sixty participants, randomly (randomisation table) allocated to two groups. After the completion of informed consent participants received treatment over three consultations with a follow up a week later. Baseline and repeated outcome measures included Numerical Pain Rating Scale, Neck Disability Index Questionnaire, Myofascial Diagnostic Scale, Algometer and Cervical Range of Motion device. The data was analysed using ANOVA tests with the p-value set at 0.05. Results: Baseline demographics and outcome measures showed that only age was significantly different between the groups. This difference was controlled for in the statistical analysis. Dry needling resulted in better treatment outcomes than the Flurbiprofen LAT patches in terms of function (cervical range of motion) (right lateral flexion p=0.043) and Myofascial Diagnostic Scale scores (p<0.001), whereas the Algometer measures and remaining cervical ranges of motion improved significantly over time in both groups, but not between the groups. Tthe Flurbiprofen LAT patches fared better in terms of the subjective reporting (Numerical Pain Rating Scale), this was not significant. Conclusion: The interventions were both effective over time, however, the needle group achieved improved functional ability and the Flurbiprofen LAT patches improved the pain outcomes with limited functional ability. Therefore the use of these modalities requires clinical judgement to appropriately administer the treatment option that the patient would best benefit from.
